IMPRCVEMENT IN IMECHANICA'L M OVEHMENTS.

Specification forming part of Lettersy Patent No. 172,802, dated Jannary 25, 1876; application filed v December 1, 1875.

Be it known vthat I', ALBIN WAR'rH, of Stapleton, in the county ofRichmond and State of New York, have invented' a new and Iming drawing,in which- Figure l represents a plan or top view. Fig.. 2 1s a rearview. Fig. 3 is a transverse section in the plane .fr w, Fig. 1. Fig. 4is a horizontal section in the plane y y, Fig. 2.

Similar letters indicate corresponding parts.

"This invention relates to certain improvements on that class ofmechanical movements which are composed of a carriage acted on by a beltthat receives a'continuous motion from some source, said carriagebeingprovided with a swivel-standard, and with apulley, from whichmotion is transmitted to a working-machine, as fully described in myPatent No. 151,457, dated May 26,1874.

My present improvement consists in combining with the carriage and thecarriage-snpporting rail, and with the traveling belt suitable supports,which retain said -belt in the proper position, and prevent the samefrom running ofl from its pulleys; also, incombining with thecarriageand its standardan arm radiating from the same, and bearing atits outer end a socket, which is openv atboth ends, and in which therod' is secured which connects the traveling carriage with the workingmachine, so that said rod can be movedin or' out, and the tension of thebelt transmitting motion to the working machine can bel adjusted;further, in the combination, with the carriage and with the rod'connecting the same 'to a working machine, of a balanceweight, whichcounterbalances, to some eX- facilitates the motion thereof over thework table. or bench; also, in combining with the carriage and itsguide-rail suitable grooved supporting-rollers, to facilitate the motionof said carriage; further,'in the combination, with the rod or standardwhich rises from the carriage, land with said carriage and the rodconnecting the same to a working machine, of

i a joint, whereby the motion of the working machine. and the operationof the apparatu are materially facilitated.

In the drawing, the letter A designates a table, on which, near one ofits edges, are secured a series of posts, B, which form the supports fora rail, C, on which travels thecar` riage D. j

From the posts, which are situated near theA ends of the table A, risestandards E F, one

of which forms the bearing for a horizontal arbor, a, While in the otheris secured avertical arbor, b.

Onl the horizontal arbor are mounted two pulleys, c c, and on thevertical arbor a single 'pulley, d, the dialneterof which is equal to Abelt,l G, is stretched round .the pulley d, over the the distancebetween the pulleys c c.

pulleys c o, and round a pulley, c, which is mounted on thedriving-shaft.

In the example shown in the drawing thisf driving-shaft is mountedbeneath the table A, but its position may be changed, as circumstancesmay require. Y

When the driving-shaft is in motion the belt", y

Gr moves with it. j This belt Il have termed the Y traveling belt.7

Y lf this belt is of great length, and it is left entirely unsupportedbetween the pulleysc c and the pulley d, it is liable to sway up andydown to a considerable extent, and also to run off from its pulleys.

These difficulties I have obviated by securing on the guide-rail C oneor more T-shaped` standards, H, on the ends of Whose horizontaly armsare secured rollers f, which support the traveling belt Gr. SaidT-shaped standards may be made adjustable on the guide-rail, so thattheir position can be changed to suit circ cumstances. tent, the weightof the Working machine, and

The carriage D is providedwith 'grooved rollers g, which travel on theguide-rail G, and A from said carriage rises a vertical rod 0r standard,I, on which arel mounted loosely a transverse bar, J, and a doublepulley, h z.

On the transverse bar J are secured two pulleys, j, and if said bar isturned in an oblique position the pulleys j compress the two strands ot'the traveling belt against the circumferencc of the pulley h, thediameter of which is equal, or nearly so, to that ofthe pulley d.

The transverse bar J is locked in its oblique position by a suitablelatch or catch, k; and if motion is imparted to the traveling belt G,the pulleys h i of the carriage are caused to revolve, while thecarriage can be freely moved on the guide-rail C without interruptingthe motion of its pulleys.

On the rod or standard I of the carriage D is mounted loosely an arm,K,Awhich is provided with a socket, l, for the reception of rod L, thatforms the connection between the carriage D and the working-machine M.

In the example shown in the drawing I have shown a machine for cuttingtextile fabrics attached to the rod L; butl any other workingmachine-such, for instance, as a drilling-machine or amortising-machine-may be substituted for said cutting-machine.

The socket lis open at both ends, so that the rod L can be passed clearthrough it, and said rod is secured in position by a set-screw, m, sothat it can be adjusted backward and forward.

Motion is imparted to the working machine by a belt, n, which extendsover the pulley i of the carriage D, and, by moving the rod L backwardor forward in its socket l, the tension of this belt can be regulated.`

vIf the belt should stretch at any time, a slight motion ofthe rod Linthe proper direction will readjustits proper tension.

On the carriage D are secured supports o o for the traveling belt, sothat the same is notv liable to run off from the pulley h.

From the bottom edge of said carriage extends a rod, p, on which issecured a weight, q, that serves to counterbalance, to some extent, theweight of the working machine attached to the rod L, so that saidworking machine can be moved over the table A with little exertion. Thismotion of the working machine is still further facilitated byconstructing the guide-rail C in the form of a cylindrical rod,and byproviding the carriage with grooved rollers g g, the grooves of whichfit said rail, so that the carriage will not only move easy in thedirection of the length of said rail, but it can also be turned on saidrail if it is desirable to raise the working machine on the table, whilethe balance-weight on one side, and the weight of the working machine onthe opposite side, keep said carriage securely down on the guide-rail.

The rod or standard I is connected to the carriage D by a hinge-joint,s, so that when the working machine is brought close to the travelingbelt it caustill be lifted off from the table A.

By these means the position of the workin g machine over the table A canbe readily accommodated to the work to be accomplished.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a mechanical motion composed of a carriage, a traveling belt, anda standard connecting'the carriage to a working machine, I

claim the combination of supports H, one or more, with the travelingbelt and the carriage, and the swivel-arm and rollers on the carriage,for throwing the carriage in or out of gear with the traveling belt,substantially as and for the purposes set forth.

2. In a mechanical motion composed of a carriage, a traveling belt, anda standard connecting the carriage to a Working machine, I claim theswivel-arm K, provided with a socket, l, which is open at both ends, andthrough which'exten ds the rod connecting said carriage to the workingmachine, substantially as and for the purpose described.

3. In a mechanical motion composed ot a carriage, a traveling belt, anda standard connecting the carriage to a working machine, I claim thecombination of a `balance-weight with the carriage, the rod connectingthe working machine to said carriage, and the swivel# arm and rollers onthe carriage, for throwing the carriage in or out of gear with thetraveli'ng belt, substantially as and for the purpose set forth.

4. In a mechanical motion constructed as above stated, I claim thecombination of groovcd rollers with the guide-rail C and4 with thecarriage D, and the swivel-arm and rollers on the carriage, for throwingthe carriage in or out of gear with the traveling belt, substantially asdescribed.

5. In a mechanical motion, as above de` scribed, I claim the combinationof a hinge-` joint with the rod or standard I and the car-` riage D,substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this26th day of November, 1875.
